perform the following steps:slip the "CLK_TRG" label on to one cable and the "JTAG" label on the otherslip the black heat shrink over the end of each cable after the printed labelscut and peel back plastic insulation, cut shield braid; nick shield aluminum and tear offnick aluminum shield around each pair and tear shielding offstrip insulation off each wire in each pairtin the end of each wire with lead-free solder, ensuring not to leave any blob of solder bigger than will fit in the hole in the boardthe plastic insulation will receed when heated, so short lengths of heat shrink tubing will be needed (see next step)place the 2 mm OD clear heat shrink tubing over the insulation of each solid color wireplace the 2 mm OD white heat shrink tubing over the insulation of each white/striped wirekeeping the lengths of exposed wire equal for all wires, use heat gun on "low" setting to shrink in placeadd a length of 4 mm OD clear shrink tubing to each twisted pair, trying to keep the existing twist and shielding in placeuse the heat gun on "high" to shrink this together; this will make the soldering step easiertie the hook-and-loop fastener around the cable to keep it coiled during the soldering step (do the same for the power cable if applicable)put PCB in PCB holder and lock in place
for each cable (JTAG on the left and CLK_TRG on the right, as seen from the side of the board with the FPGA), perform the following steps:push one of the pairs of wires through the board in the appropriate holes (see map on this sheet for what color pairs go where for the cable you have)using a clean soldering tip, tack the two wires in place with some lead-free solderwhile reheating each connection, ensure the twisted pair is fully seated and no exposed metal is visible below the PCBrepeat for the other three twisted pairstrim any solder/wire from the board in excess of 1 mm, being careful to discard any cuttings (so they do not cause shorts on the PCB when in operation)

prepare the following:cut two lengths of 8 mm OD black heat shrink tubingcut four lengths of 2 mm OD white heat shrink tubingcut four lengths of 2 mm OD clear heat shrink tubingcut four lengths of 4 mm OD clear shrink tubinghook-and-loop fastenercut cat7 cable so you have two equal length halves (measured from end of connector to cut location)print out an 11 mm OD heat shrink tubing label that says, "JTAG" and another that says, "CLK_TRG"

the solid color wire goes in the rectangular pad;the companion striped or white wire goes in the round pad
the end result should look something like this:
